Why can the County Inspector's solution be called partial?

He fixes the machine's pace but not social loneliness

The governing concept is the difference between solving a mechanical fault and solving the complete educational problem. The County Inspector discovers that Margie's Geography sector is set too fast, so he slows it to an appropriate level and temporarily removes the machine's panel. That action addresses the immediate technical difficulty, but Margie still studies alone at home with a machine and has no classmates with whom to discuss lessons, play, or share experiences. Option A is correct because it captures both sides of the situation. Option B is false because the inspector does not destroy the old book; C and D contradict the events. His solution is useful, but it cannot restore the social dimension of schooling.
